Letters Patent No. 111,979, dated February 21, 1871; antedated February 6, 1871.

IMPROVEMENT IN CORN-PLAN'l'ERS.

The Schedule referred to in these Letters Patent and making part of the same..

To all whom fit may concern Be it known that I, Josnrn SCHOTT, of Peoria, in the county of Peoria, and State of Illinois, have invented a new 'and valuable Improvement in Corn- Planters and I do hereby declare that the following is a full, clear, and exact description of the construotion and operation of the same, reference being had to the annexed drawing making a part of this specication, and to the letters andfigures of reference marked thereon.

Figure l of the drawing is a side view of my invention.

Figure 2 is a top view the saine.

Figure 3 is a central longitudinalsection.

Figures 4, 5, 6, 7 and 8 are details.

My-invention relates to corn-planters, and consists in a novel arrangement of devices intended to serve as a valuable and eicient apparatus for thepnrpose named.

A A of the drawing represent two longitudinal bars, the rear ends of which are formed intoA guidinghandles,'and the front ends brought together, as shown,

so as to form a frame in the shape of aharrow. These bars are united and kept in place by a series 'of rods with bolt-heads, threads, and screw-nuts, as the drawing represents.

The letter B represents a large wheelor roller, arranged to revolve on the ground and between the bars A, as shown.

G represents au eccentric, rmly attached to the side of the roller B, for the uses and purposes hereinafter mentioned.

rlhe letter c represents the rear cross-bar of the frame, which is arranged to rotate in its bearings, and is actuated by the wrench c, which wrench is held in place and tightened or loosened by` a thread and nut, as shown.

D represents a rod, made rigid in the front cnds'of the bars A.

` To the ends of this rod, respectively, are aiXed the pendent markers E E.

G represents 'a sharp colter, arranged between the front ends of the bars A, and made adjustable there in by means oi' a slot, g, and' the bolt' that passes through the same, as shown.

g rlhe rear side of colter G is made circular in form, and is split so as to form a groove adapted to receive and hold the front ends of the bent plates H, next mentioned.

H represents two plates, the front ends of which are pressed closely together and passed into the groove on the rear side of the colter G, while their rear ends are bent outward, as shown, so as to pass around and clasp the lower end ot the dropping-tube, as mentioned hereafter. i

I make a series of openings, una, in the-upper,

turned-up front end of the plates H, to provide means for attaching the team. to the planter and regulate the altitude ot' the point of such attachment, at the will ofthe operator. p

The letter o is a thumb-screw, working upon the top of the rodpD, to regulate the rigidity thereof.

. Krepresents a bent lever, having a slot, fr, at its front end, and its rear end formed in a. hook-shape, adapted to work on the eccentric C. This lever is pivoted to a side bar, A, as shown.

, L is a spring, attached to andY made adjustable ou a side bar, A, as shown, at its rear end, while its front end is connected with the lever K by means of the cord or chain t.

M represents the hopper, formed with springs t and u, and also with a larger rectangular opening in a horizontal direction with the side bars, in which the sliding block N is operated, as hereinafter described.

The letter/v represents a sliding plate, arranged to work vertically inside the hopper, and is actuated by means of the lever K, working by its slot on the pin y, which pin is firmly attached tol said sliding plate.

The letter h represents a diagonal slot, formed in -sliding plate t'.

'lhe letter N `represents a sliding block, which lmoves longitudinally with the side bars and inthe hopper of the machine, as shown. It has an openingfor the passage of the seeds downward,.inarked la on thel drawing, which lopening may be enlarged or de-.

position in the lower end or conduit-tube 'of the hopper, and held in place partly by the thumb-screw S, as shown.

To operate my device the team is attached in the proper opening of the turned-up plates, and the seed placed in the hopper. As the machine is drawn forward the colter cuts a furrow for the seeds, and, as the roller revolves, the cam O operates the bent lever in such manner that the 'block N is moved back and forth, and the plate '1J is moved up and down by the same-rotation of the roller. The seed passes downward through ,opening 7e of the sliding block and a ,similar vopening in the base-block, and f'om thence to the lower point of the kangle formed by the spring plate R, from whence it is forced to the ground by the lower end of plate c, operated by the spring L. After thus reaching the furrow formed by the colter, it is covered-hy the roller B. v

In order to aid inthe process of dropping the seed fr om the hopper in desirable quantities, I construct an adjustable block with a brush on its lower end, in the-form shown on fig. 7, and arrange it vertically-in the side of the hopper,'so that the brush shall par`y tially cover the opening in ythe sliding block. By a proper adjustment of this block and br-ush the seed may be permitted to pass downward in such quantities, at each Yrevolution of the roller, as Ythe operator may desire.

the furrow to follow that beingplante'd'.

-What I claim asv my inventioln and desire to secure by Letters Patent, is-

l. The adjustable colterr, in combination with the bent .plates H, when constructed and arranged substantially as and for the purposes herein specified.

2. The slidingr block N, sliding plate c, and block and brush, iig. 7, combined with the lever K, cam C, and springs L and R, when constructed and arranged to operate substantially-as and fer the purposes speciied. Y Y

In testimony that I clailn the above I have hereunto subscribed my name in the presence of two witnessesQ Witnesses:
